I can't believe nobody has commented on this one. Road Rash was a brilliant game, I think EA were really in a sweet spot with the Mega Drive, wth this, EA Hockey, John Madden and Desert Strike the standouts for me.
I remember saving up loads of cash to buy a better bike, then getting one that was so fast I couldn't control it

And also trying to knock the police off their bikes, even though I knew it was impossible. Running back to the bike after a big crash before the cops arrived to arrest me... all good, innocent childhood fun! Would love to see this on the Wii virtual console!
